BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides minimalist replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete POSIX environment for any small or embedded system.

emlog is a Linux kernel module that makes it easy to access the most recent (and only the most recent) output from a process. It works just like "tail -f" on a log file, except that the storage required never grows. This can be useful in embedded systems where there isn't enough memory or disk space for keeping complete log files, but the most recent debugging messages are sometimes needed.

EVBU simulates the execution of a 68HC11 microcontroller as well as the BUFFALO monitor program that provides a command line interface to executing and debugging programs. A graphical waveform panel allows simulation of 68HC11 peripherals like timers, input capture, etc. Additional features include symbolic debugging and cycle counting.

MiniGUI is a mini graphical user interface (GUI)
support system for Linux that provides an
event-driven API for applications. It makes it
possible for an application to create multiple
windows in multiple threads, and can draw in these
windows without interfering with each other. A
Graphics Abstract Layer (GAL) and an Input
Abstract Layer (IAL) are provided for
compatibility with many graphics engines,
including SVGALib, LibGGI, and X. It provides
native support for many image types including GIF,
JPG, PCX, LBM/PBM, and BMP, TrueType and Adobe
Type1 fonts, and GB2312 and BIG5 charsets.

The Mozart system provides state-of-the-art support in two areas: open distributed computing and constraint-based inference. Mozart implements Oz, a concurrent object-oriented language with dataflow synchronization. Oz combines concurrent and distributed programming with logical constraint-based inference, making it a unique choice for developing multi-agent systems. Mozart is an ideal platform for both general-purpose distributed applications as well as for hard problems requiring sophisticated optimization and inferencing abilities.

SRecord is a collection of powerful tools for manipulating EPROM load files. It understands a number of file formats including Motorola S-Record, Intel hex, Tektronix hex and binary, for both input and output. SRecord filters include cropping, filling, splitting, joining, and more. All filters may be applied to all file formats.
